Description

Add Power. Replace your restrictive factory throttle body with a free-flowing GMS twin blade for more power and better acceleration. This throttle body has been dyno proven to add up to 22 mid-range HP and 11 peak HP when combined with an intake and an exhaust, making it one of the most cost-effective modifications you can make to your S197 GT.

62MM Twin Blade. Your factory throttle body chokes your engine when it needs air the most. Maximize your mods by making sure your engine is getting the air it needs to perform its best with this generously sized 62mm bore twin blade throttle body.

Lightweight Aluminum. Unlike heavier steel parts, Granatelli's twin throttle body has been made from durable but lightweight cast aluminum. This throttle body features a natural finish for a pure performance look under the hood.

Bolt-On Installation. The GMS Twin Blade throttle body is designed to install in around 45 minutes using basic hand tools. It includes a new throttle position sensor (TPS) for easy installation.

Application. This GMS 62mm Twin Blade Throttle Body is designed to fit the 2005 to 2010 Mustang GT and 2007 to 2009 GT500 with an included adapter. It is compatible with the stock manifold but does require an aftermarket cold air intake for proper fit.

Great Product

This throttle body is simply awesome. Combinded with the BAMA Tune, The pedal is very punchy and there is a very satisfying power increase.
It only gets 4 stars because of the following.
The O-ring ( Gasket ) that they tell you to retain
will most likely be useless due from stretching. I had to buy a new one from FORD. Also they dont tell you that the two studs on bottom of throttle body need to be removed. I had to buy a stud remover they were so tight. This is the worst one of all. After installing the larger throttle body, and required spacer inbetween, the PCV hose is not long enough that plugs into the side of the intake tube and extends to the valve cover stem. That hose snapped when i attempted to try and connect it. I Also had to buy a new one from ford.
Dont let those items stop you from getting this product. Its just better when you can be prepared.
The fact that the whole assembly is already attached on arrival is worth the hassle alone.
If Grannatelli provided a heads up on the above, I would have given it 5 stars, because I would have been better prepared for this install.

Tune Required? I noticed one of the other throttle bodies offered by AM required a tune, this one doesn't say anything about a tune though. I'm guessing this particular throttle body doesn't require a tune?

Yes it will fit. The ford racing intake has the same throttle body mount as stock.
I would recommend getting the polished 62mm ford racing throttle body if you have that intake though it will match really well.

Outstanding product!!! Very easy to install!! Huge noticeable difference in throttle response and power!!! One of the best bolt ons for the $. Only problem is plenum covers will not fit back on intake manifold without custom fabrication.

Installed this to go with an already installed JLT cai series 3 and BBK ceramic long tubes with the shorty x-pipe and Flowmaster catbacks. The overall gain with this final add to that combination is incredible! Much more than I thought, combined with the Ford Racing Rear Axle Assembly I had installed with the 3.73's and the TCI Torque Converter with the TCI Streetfighter tranny, the stang is sick! Absolutely sick!

installed along with cl cold air intake and bama's race tune from AM and oh my god what a difference. lower studs come right out with a pair of needle nose vice grips with no damage to the stud and used some 3/8 rubber fuel line for the breather tube issue on the pass side.

I am not a car guy...let's start off with that. I bolted on the GMS twin 62mm throttle body and also installed the JLT Performance Series 3 Cold Air Intake. The used the Bama X4/SF4 Power Flash to set things up. Fired up my 2005 Mustang GT and WOW!! Runs great, sounds even better!! I need to go out for a ride now and really test it out...........

I have this TB paired with an Airaid CAI and it really opens up when I floor it. I also received a tune to pair everything up. No complaints here.....installation was easy and there was no need to adjust the voltage on the TB which is the case with the BBK TB. I purchased a BBK TB a while back and never could get the voltage to match the factory TB so I returned it. The GMS was a good choice and almost a month later I've had no issues with it at all. I highly recommend a tune. I'm running 93 octane and have it tuned for 93R...love it!

Still have not mastered all the power this throttle body gave me. It idles around 2 grand at start up when cold ...then simmers down. Lost one half a mile per gallon...what else. Getting 14.3 now, Hit second with traction off almost lost it. You simply CANT nail this car its TOO FAST! What a feeling. This throttle body UNLEASHED THE CAR...it was choking with the stock unit.
